After a fourteen year hiatus, it was revived for a fifth series, hosted by Celia Pacquola and featuring a guest judge each episode.

[3] Each contestant is dressed in appropriate costume, has some brief banter with the host, and is then invited to "walk through the blue door" onto a hidden set.

Typically they will be asked in-character questions by the ensemble cast and challenged to provide information about the scene, including the names of characters or objects.

At least twice during each episode (to cover set-up and costuming for the live audience), footage is shown of each of the four participants performing a challenge, often on location, which was filmed earlier in the week.

These include a commentary booth where the contestants have to comment on an unfamiliar subject, an office where they are being interviewed or interrogated (by police, customs officials, etc.

The third series also introduced an additional segment in which Gleisner highlights a "real life" Thank God You're Here-style situation, such as the infamous Guy Goma BBC interview and frequently, that of politicians forced to improvise answers under pressure.

The fourth season introduced a different segment, where Gleisner points out that he believes an Australian cricket player is able to endorse anything, and presents a falsified advertisement where a retired Australian cricketer (Damien Fleming) attempts to endorse an also falsified company of a completely random field (such as a French restaurant or sewage processing plant).

Since series 5, the format of the show has been tweaked slightly as the performers no longer participate in any "during in the week" scenes, which were in previous seasons filmed on-location with the ensemble cast.

This ensemble was also used in many of the mid-week assignments, fulfilling the roles of customers or members of the public with whom the guests must interact in a real-life setting.

Special guests have included Damien Fleming, Dan O'Connor, Melissa Tkautz Natalie Bassingthwaighte, Kate Ceberano, Alan Fletcher, Kimberley Davies, Matt Welsh, Mark Holden, Ryan Moloney, Simon Burke, Greg Evans, Nikki Webster, Mick Molloy, Todd McKenney, Poh Ling Yeow, Grant Denyer, Miguel Maestre and The Veronicas.

Other guests including Jane Hall, Andy Lee and Don Burke have appeared as mock presenters in the locational challenges.

Host Shane Bourne and judge Tom Gleisner appeared on Rove Live on 11 April 2006, to promote the show after the first episode had screened.

With Global Television Studios in Nunawading getting ready to shut down,[1] Series 4 started filming at Melbourne Showgrounds in Flemington, in the shed normally used as the Poultry Pavilion.

The new venue was an issue for audio, as there was no soundproofing, so the nearby railway line often interfered with scenes, and Gleisner remarked that if it had rained, they would have been "stuffed".
